Hi,

I'm using Arduino IDE and 'ESP32-C3-WROOM-02-N4.

I can't get UART1 no matter which pins I used.

Anyone managed to get it to work on Arduino IDE?

hi,

thanks for the link.

I am able to flash the esp32-c3, but not able to get data from uart1.
NO matter which free pins I used for the hardware serial, i don't get any response.

I can see the data from uart0 (which are shown on the Arduino serial output console).

Thanks.

Have tried to use UART1 with all the GPIO pins, but nothing is coming back (tried the code on ESP32 Wroom and it was fine).

Am using ESP32-C3-WROOM-02-N4.

I am trying to get softserial to work on esp32-c3. Not sure if you've tried this before? Did you manage to get it to work?

Hi,

The UART1 (hardware UART) is not exposed on the pin out, so I can't use it.
Will have to use ESPSoftwareSerial to get data thru UART with another module.

Anyone got experience with ESPSoftwareSerial on ESP32-C3? It works well?

Hi, The ESP32-C3 has 2 hardware uart. How do I use the 2nd uart? I've tried // ESP32 C3 SERIAL1 (second UART) HardwareSerial mySerial1(1); int rxPin=4; int txPin=5; void setup() { Serial.begin(115200); pinMode(txPin,OUTPUT); pinMode(rxPin,INPUT); mySerial1.begin(115200, SERIAL_8N1, rxPin, txPin); } ...

hi, I am developing a software in Arduino IDE for ESP32-C3. I want to use UART1 to communicate with another device using AT command. I've tried using SoftwareSerial and HardwareSerial but can't get it to work. I just need to be able to send "AT?" and get a "OK" as reply. Any help? Codes: // ESP32 C3...

Hi,

Can your phones detect those BLE devices?

Hi,

I'm not clear. Is there a pulse counter or not?

nice project!
